Description

[Detailed description of the invention]

[0001]

[Industrial application field] The present invention relates to an airtight structure of a house, in particular,
The present invention relates to an airtight structure suitable for a peripheral portion of a ceiling plate that separates a lower floor of a house from an upper floor (including an attic).

[0002]

2. Description of the Related Art A house with high airtightness is required especially for a house for a cold region having a low outside air temperature. FIG. 4 is an explanatory view showing an example of a conventional cross-sectional structure of a peripheral portion of a ceiling plate. An outer peripheral edge 10 is formed of a column having a rectangular cross section,
It is attached to the inside surface side of. The outer wall panel 1
A gypsum board 14 for constituting the inner wall surface of the building is adhered to the inner side surface of the building 2, and the edge 10 is fixedly attached to the surface of the wall gypsum board.

[0003] A ceiling gypsum board 16 as a ceiling member that separates the lower floor from the upper floor is attached to the lower surface of the outer peripheral edge 10. For example, the ceiling gypsum board 16 is mounted and installed through a resin joiner 20 having a substantially U-shaped cross section and fixed to the lower surface of the outer peripheral edge 10 with a nail 18 or the like. . That is, this is performed by engaging the end of the ceiling gypsum board 16 between the legs of the U-shaped portion of the joiner 20. In addition, the attachment of the gypsum board 16 on the end side is not limited to the structure using the joiner 20, but the outer peripheral edge 10 and a plurality of inner peripheral sides attached to the wall to which the outer peripheral edge 10 is attached. Ceiling plasterboard 16 by beveling (not shown)
Is supported.

[0004]

However, according to the above-described conventional structure for mounting a ceiling support member, the sealing performance with respect to a wall surface such as an outer peripheral edge 10 which is a ceiling support member mounted on a wall is not perfect. From that, downstairs and upstairs,
For example, the airtightness between the living room and the attic becomes poor. In particular, in a building in a cold region, such poor airtightness lowers the heating effect, so that sufficient airtightness is required.

[0005] Such poor airtightness is caused by the outer peripheral edge 10.
Is made of a material that does not easily expand and contract due to a temperature difference or the like, a wooden one is used, and therefore, it is difficult to secure a hermetic seal with the wall plasterboard 14. . That is, it is based on the fact that both the wooden outer peripheral edge 10 and the wall gypsum board 14 cannot maintain the close contact between them because both have low elastic coefficients.

Further, even when a resinous joiner 20 is used as shown in FIG. 3, the ceiling gypsum board 16 needs to be supported by the resinous joiner 20, so that the joiner 20 has a certain degree. It is necessary to have rigidity, and it is not possible to ensure sufficient adhesion between the outer peripheral edge 10 and the wall gypsum board 14 similarly to the outer peripheral edge 10 made of wood.

[0007] As described above, in the conventional airtight structure of the periphery of the ceiling, the airtightness between the downstairs and the upper floor cannot be sufficiently ensured, and the heating efficiency is lowered in a cold region or the like. was there. This problem is particularly remarkable at the periphery of the ceiling, but the same applies to other joints.

[0008]Purpose of the invention  The purpose of the present invention is to solve the above problems.
The purpose depends on the skill level of the workers.
The airtight structure of a house that can realize a reliable airtight seal without
It is still another object of the present invention to provide an airtight structure at the periphery of the ceiling.

[0009]

To achieve the above object, according to an aspect of an airtight structure of houses according to the invention of claim 1, water
The two surfaces of the flat material are in surface contact with other members, and a notch is formed at a corner where the two surfaces contact each other, and a deformable member having a volume larger than the notch volume is compressed and deformed into the notch. It is characterized by being accommodated.

[0010] The hermetic structure of a house according to claim 2 comprises a ridge fixed adjacent to a wall surface of the structure, and a ceiling plate having a peripheral portion fixed to a lower surface of the ridge. A notch is formed at a corner of the edge where the two surfaces facing the ceiling plate intersect, and a deformable member having a volume larger than the notch volume is compressed and deformed and accommodated in the notch.

The airtight structure of the house according to the invention of claim 3 is as follows:
A ridge fixed adjacent to a wall surface of a structure, a ceiling plate having a peripheral portion fixed to a lower surface of the ridge, and a periphery fixed to cover a lower surface of the peripheral portion of the ceiling plate and the wall surface adjacent thereto. A notch is formed at a corner of the surrounding edge where two surfaces facing the lower surface of the ceiling plate and the wall face intersect, and a deformable member having a volume larger than the notch volume is compressed and deformed into the notch. It is characterized by being accommodated.

[0012]

According to the airtight structure having the above-described structure, the horizontal member such as the rim or the surrounding rim has the notch at two corners facing other members, for example, the ceiling plate and the wall surface. Then, by accommodated the deformable member is compressed and deformed in the cutout portion, the horizontal
Seal the ventilation path over the entire joint of the material . As described above, since the joint of the horizontal members has an airtight structure, the present invention greatly contributes to improving the airtightness of a house particularly in a cold region. In particular, when the present invention is applied to an airtight structure at the periphery of the ceiling, the flow of air between the downstairs and the upper floor is cut off, and in cold regions, etc., when the lower floor is heated, from the attic. It is possible to reliably prevent cold air from entering, and it is possible to improve the heating efficiency.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows an example of an airtight structure at the periphery of a ceiling according to an embodiment of the present invention. Elements similar to those of the conventional mounting structure shown in FIG. 4 are denoted by the same reference numerals. .

A feature of the present invention is that a notch is formed at a corner of the outer peripheral edge 10. In this embodiment, the mounting surface on the wall gypsum board 14 side and the ceiling gypsum board 16 are provided.
A cutout portion 22 is formed at a corner that is an intersection with the side mounting surface.

FIGS. 2A and 2B show the outer peripheral edge 1.
It is an explanatory view showing a configuration of a notch portion and a deformable member of 0,
As shown in FIG. 1A, the cutout portion 22 is formed by being cut out so as to have a substantially right inner angle.

Then, the deformable member 2 is formed over the entire area of the notch 22.
4 is loaded. The deformable member 24 is formed in a substantially prismatic shape, and when loaded into the cutout portion 22, as shown in FIG.
And a cross-sectional shape having a size such that it partially protrudes from both the ceiling member-side mounting surface 10b.

The deformable member 24 is provided on the outer peripheral edge 10.
Is mounted on the wall gypsum board 14 and the resin-made joiner 20, and a member capable of maintaining sufficient airtightness at that portion is used. For example, “Epto Sealer” (trademark) manufactured by Nitto Denko Corporation Is preferred.

The deformable member 24 has a notch 22 in the outer peripheral edge 10.
It is not necessary to fix to the notch portion 22 when the outer peripheral edge 10 is attached.

When the outer peripheral edge 10 is mounted and fixed as shown in FIG. 1 with the deformable member 24 loaded, the gap between the wall gypsum board 14 and the deformable member 24 and the space between the resin joiner 20 and the deformable member 24 are increased. Each of them is almost completely sealed. This sealed state is ensured over the entire inner peripheral surface of the wall, so that the flow of air is substantially blocked between the room below the floor and the space such as the attic above the floor. Therefore, it is possible to effectively prevent cold air from entering from another floor during heating. Moreover, by performing a local hermetic seal at the corner of the outer peripheral edge 10,
An effective hermetic seal can be realized over the entire periphery of the ceiling.

Next, FIG. 3 shows an example in which a cut-out portion is formed at the periphery of a decorative portion as a ceiling support member. The decorative rim 26 is attached below the ceiling member, that is, the ceiling gypsum board 16 as a ceiling member is supported on the upper surface side of the decorative rim 26.

In this embodiment, the cut-out portion 22 is formed at a corner which is an intersection between the wall-side mounting surface of the makeup surrounding edge 26 and the ceiling member-side mounting surface. Then, the notch 22 shown in FIG.
As in the case of (1), the deformable member 24 is loaded and mounted. The material of the makeup periphery 26 may be wooden or resin.

As shown in the figure, since the deformable member 24 is attached in a state of being pressed against each end of the gypsum board 26 on the inner side of the wall portion 28, the makeup surrounding edge 2 is attached.
Even if there are gaps between the wall 6 and the wall portion 28 and the ceiling gypsum board 16, it is almost completely sealed by the deformable member 24. Therefore, the flow of air between the lower floor and the upper floor is cut off, and there is no flow of air from other floors as in the case of the embodiment of FIG. 1, and the indoor heat insulation can be improved.

The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the present invention. For example, the shape of the cutout portion 22 formed on the outer peripheral edge 10 or the makeup surrounding edge 26 is not limited to the shape having the substantially right inner surface as in the above-described embodiment. It is also possible to have the notch 22 having. In that case, it is preferable that the shape of the deformable member 24 is also formed in a column shape having a radius matching the circular shape. Further, as the material of the deformable member 24, various materials such as synthetic resin or rubber can be used as long as they are members having sufficient elasticity to maintain airtightness.

[0025]

As described above, according to the hermetic structure of the house according to the present invention, good airtightness is required over the entire joint area where the two surfaces of the horizontal member are in contact with each other. The airtightness of a house for a cold region can be greatly improved. In particular, if the present invention is applied to an airtight structure at the periphery of the ceiling, it is possible to cut off the air flow in the rooms downstairs and upstairs, thereby improving the heat insulation of each room.
In particular, in a cold region, the indoor heating efficiency can be improved.
